Linux kernel
Linux kernel was created by Linus Torvalds in 1991, with the initial release in 1991 as version 0.02. Over the years, it has seen significant milestones such as adoption by the GNU Project, transition to the GNU General Public License version 2, and support for POSIX APIs, Unix software, and various hardware architectures. Notable version releases like Version 1.0.0 in March 1994 and Version 2.0.0 introducing symmetric multiprocessing have marked its evolution. The kernel has continuously evolved with additions like support for Pentium 4, Itanium processors, new file systems, and capabilities, making it a robust and versatile platform.
Linux has gained immense popularity and value, with over 53% of developers working on Linux and 27% on Android. It powers a vast number of websites and all of the world’s top 500 supercomputers. The kernel’s development is fueled by a community of 5000-6000 developers, with contributions from companies like Intel and Red Hat. Linux is accessed through various distributions, each offering different levels of customization and additional features. Its technical aspects, including architecture, memory management, virtualization capabilities, security mechanisms, and communication protocols, make it a highly versatile and reliable operating system kernel.
